Description

Miasmata is a first person adventure in which the player must try to cure himself from a plague, while stranded on an abandoned research island. The plague causes rapid dehydration and periodic fevers, which the player can counteract by drinking regularly and crafting medicine at crafting stations on various parts of the islands. To craft medicine the player must collect local flowers and fungi. Aside from fever reducing medicine there are also recipes that will improve the player's perception, strength and agility.

Most of the time the player will be exploring the island. The player starts with a blank map which can be filled in with the terrain's features through triangulation. The player can use the compass to determine the direction of man-made landmarks. Through triangulation with known landmarks the player can mark his or her location on the map. And once his or her location is known, the player can mark the direction (but not distance) of unknown landmarks. Once the direction of a landmark is oriented from two different positions, its exact location becomes known on the map, revealing more and more features of the world on the map.

The player's primary concerns are succumbing to the plague and environmental hazards, such as falling from cliffs or drowning when swimming when fatigued, but there is also something else lurking in the foliage... The game makes use of momentum, so when running down a hill the player will not be able to stop instantly and might hit a tree hard or even trip on uneven terrain.

The game uses a day-night cycle. The player can save only by activating lamps or candles or sleeping in a bed.
